A nifty little feature of nvram is the ability to delete all of the firmware variables you’ve created. This can get helpful if you’ve got a bunch of things that you’ve done to a system and want to remove them all. If you run nvkram followed by a -p option you’ll see all of the configured firmware variables: nvram -p If you run it with a -d you’ll delete the given variables that you define (e.g. boot-args): nvram -d boot-args But, if you run the -c you’ll wipe them all: nvram -c

All of these can be enabled and managed from the command line as well. The traditional way to enable Apple Remote Desktop is using the kickstart command.…

Backup macOS Server 5.2 Settings On Sierra
We covered using Time Machine Server previously. Here, we’re going to look at backing up the settings of an OS X Server. To do so, we’re going to install a little app called Bender from the great folks at Robot Cloud. You can download that from http://robotcloud.screenstepslive.com/s/2459/m/5322/l/94467-bender-automated-backup-of-os-x-server-settings. Once downloaded, run the package installer.

Choose who you wish to install the software for and click Continue. I’d go ahead and install Bender at the default location, so click Install. Once the…
